CAR-AXLE.

SPECIFICATION forming part of Letters Patent No. 551,746, dated December17, 1895.

Application filed Tulle 29, 1895. Serial No. 554,417. (No modelr) T0 allwhontit may concern:

Be it known that I, SAMUEL L. DENNEY, a citizen of the United States,residing` at Atlantic City, in the State of New Jersey, have inventedcertain new and useful Improvements in Car-Axles; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specication.

My invention has relation to improvements in car-axles of that class orstyle denominated divided axles,7 which are intended to permitoppositely-mounted wheels of the axle to accommodate themselvesautomatically to the strains, variable rotation and different exigenciesof motion arising during the progress of the car over the track, andespecially around curves.

The present invention has for its object to improve my former invention,as shown and described in my Letters Patent No. 366,307, dated July 12,1887, wherein are disclosed an axle divided near its mid-length, theadjacent middle portions being enlarged to form the frustum of coneswith their bases contiguous, and a divided and ianged coupling-sleevefitted to the conical portions and secured in position. In the presentinvention I do away with this divided coupling-sleeve and provide thenew and improved couplin gsleeve herein shown and described.

I have fully and clearly illustrated my invention in the accompanyingdrawings, wherein- Figure l is a front view of wheels carrying a dividedaxle and having my improved coupling-sleeve mounted thereon, the sleevebeing shown in central sectional view. Fig. 2 is a transverse section ofthe axle on the line no and' end view of the coupling-sleeve cap.

Referring to the drawings, A A designate car-wheels mounted in the usualmanner on the respective portions of the divided axle B B substantiallyas shown inthe drawings. The inner middle and adjacent parts of thedivided axle are cach enlarged, as seen at 1 2, to form a frustum of acone, the bases thereof being arranged contiguous, as shown, so thatwhen the parts are arranged in operative relation they will present theappearance of a double cone united at the bases.

'C C designate inner sleeves iitted over the conical portions of therespective parts of the axle and for this purpose are formed withoppositely-arranged conical interiors and plane outer surfaces,preferably round, as shown, and in length stop short of the meetingbases of the cones of the axle. The sleeve C is lformed and arranged toproject a determined and requisite distance from the end of the outersleeve, as at 3, in order that it may be adjusted on the axle as'desiredand may be necessary. The inner sleeve C is formed with an annular endflange 4, against which the end of the outer sleeve abuts. This sleeve Cis preferably made of open-hearth steel and is firmly and securely fixedin the outer sleeve by hydraulic pressure or other proper power, thematerial named being well adapted to withstand the strain consequent onforcing this sleeve into position in the outer sleeve.

D designates the outer coupling-sleeve fitted over the inner sleeves andconstituting the means for holding the latter' in operative positionsand relation. This coupling-sleeve D is preferably a straight end planecylinder and is formed with an annular end flange C2, preferably formedwith an annular recess or shoulder 7, in which the end flanges of theinner sleeve C ts, as shown. On the outer end of the coupling-sleeve Dare formed exterior screw-threads S, over which iits a fastening orclamping and adjusting cap or nut E, which is held in a set or adjustedposition by means of a set screw or screws 9, as shown in the drawings.This cap E bears against the inner sleeve C and affords the means foradjusting that element on the axle. Between the end of the sleeve C andthe cap E adjacent to the axle is a recess 10, in' which may be fitted apacking to prevent the escape of oil or other lubrication.

By making the sleeve D straight, plane and continuous, as shown, I doaway with the middle meeting anges of the two-part sleeve shown in myformer patent cited, which flange is sometimes in the way of structuresor machinery located under the car, especially in tenders tolocomotives, and I also secure greater strength in the coupling bydisposing IOO of the holding and fastening bolts, which are liable tobecome loose and sometimes break.

To assemble the elements of my invention the sleeve C is secured in theouter sleeve, as specified, and then the two are arranged on the axleand then the adjusting and holding cap is fitted and adjusted in placeand the coupling is complete.

Any wear of the parts is readily remedied byadj ustment of the cap E onthe outer sleeve and against the movable sleeve C.

llavingthus described my invention, what I claim, and desire to secureby Letters Patent, is

l. As an improvement in canaxles, an axle divided near its mid-lengthand each end of the adj acent parts being conical and arranged withtheir bases contiguous in combination with two oppositely arranged andconical bored inner sleeves, an outer coupling-sleeve over the innersleeves, and a fastening and holding cap on the outer sleeve,substantially as described.

2. As an improvement in car-axles, an axle divided near its mid-lengthand each end of the middle parts being conical and arranged with theirbase adjacent in combination with the outer coupling sleeve D, the innersleeve C firmly iixed in the sleeve D, the inner sleeve C, adjustablyfitted in the outer sleeve, and the adjusting and fastening cap Esubstantially as specified.

As an improvement in car-axles, an axle divided near its mid-length andeach end of the adjoining parts enlarged to form the frustum of a cone,and having annular flanges at the meet-ing bases, in combination with acoupling sleeve formed with an interior to lit one end of the cone ofone part of the axle, an adjustable sleeve on the other conical part ofthe axle, and fastening means to hold and adjust the coupling inposition.

4. A coupling for a divided car-axle having adjacent cone-shapedterminations at the meeting parts of the axle and annular [ianges at thebases thereof, sleeves 011 the cones of the axles, an outer couplingsleeve, and a fastening and adjusting means to hold and adjust the partsrelatively.

In testimony whereof I affix my signature in presence of tWo witnesses.
